"Vladimir Yelchenko met with UN Deputy Secretary General Jan Eliasson. They discussed Vladimir Putin’s illegal stay in Crimea. Yelchenko also drew Jan Eliasson’s attention to concentration of Russian armaments along the Russian-Ukrainian border in Crimea and Donbass," the mission said on Twitter.

Putin arrived in Crimea on Friday to meet with permanent members of Russia’s Security Council after a recent attempt of an act of sabotage on the peninsula on the part of Kiev.

Kiev believes such visits by Russian officials are illegal and the Ukrainian Foreign Ministry expressed protest.
